Movie Clips

Hi, I have a movie clip which I named dropM. With in this movie clip is a series of buttons. However, on the main stage, i have used some action script. Eg

 
dropM.onRollOver = function() {
    tellTarget ("dropM") {
        gotoAndStop(10);
    }
};
dropM.onRollOut = function() {
    tellTarget ("dropM") {
        gotoAndPlay(11);
    }
};


Now the buttons within this movie clip dont work. Anyway around this so the buttons work as well.
Thanks

Daniel
